What is file transfer and how does it compare to file sharing?

File transfer is the process of moving digital files—like documents, images, and video—from one location to another. These locations might be physical, like the local hard drive storage in your laptop, or digital storage solutions like Dropbox.

If you’re familiar with this concept, you’ll no doubt have also heard references to file sharing in the same context. While the two terms are often used interchangeably, they in fact refer to two distinct processes:

  • File transfer is a way to send a copy of a file to another location or device

  • File sharing is the process of providing other users with access to an existing single version of a file via the Internet and cloud-based technology

For small businesses, startups, and solopreneurs that rely on sending large files to their customers, finding the right file transfer solution is critical.

There are many forms of file transfer, and we’ll dig into each of these, so you can make an informed decision on what’s best for your business.

Why is file transfer so important for solopreneurs and startups?

A solopreneur is a business owner who doesn’t have any staff other than themselves to carry out the main operations of the business. Some common types of solopreneur include:

  • Consultants and coaches

  • Bloggers

  • Course creators

  • eCommerce sellers and “dropshippers”

  • Podcast, streaming, and video content creators

While large businesses and enterprises have dedicated IT teams and company-wide technology solutions, solo entrepreneurs and startups will often have to rely on themselves and their own devices.

This means that, as a solopreneur, you’re solely responsible for having the technology to deliver what you need. Whether that’s content creators needing to transfer large raw video files between devices, or consultants sharing documents with clients.

Types of file transfer

There are many ways to transfer files, both online and offline, each with their own benefits and use cases. Five of the most common types of file transfer include:

  • Email attachment

  • File transfer website

  • Cloud storage

  • Removable storage, like an external hard drive or USB flash drive

  • FTP (File Transfer Protocol)

There is no single best option and many of these approaches have specific advantages for depending on the needs of a given situation. To help make sense of it all, we’ll now explore each method in more detail.

Email attachment

An email attachment is a method of file transfer that involves sending a copy of a file to someone via email. A copy of the file is saved to the email, which is then sent and picked up by the email client of the recipient.

Advantages of email attachments for file transfer

  • Quick and easy—attaching a document to an email is as simple as drag-and-drop

  • Free—many popular email clients will allow you to send and receive email attachments with a free email account

Disadvantages of email attachments for file transfer

  • File size limits—you typically can’t send more than around 25 MB via email attachments.

  • Security—sending a file via email means creating a copy that exists forever and could be forwarded to anyone.

  • Lack of control—once it’s sent, it’s sent. There’s no retrieving or updating an email attachment once it’s gone over to the recipient, even if you need to fix a typo or send the wrong file by mistake.

When to use email attachments

In the modern cloud-based computing era, email attachments aren’t really necessary. They’re fine if you just need to send something as soon as possible and aren’t worried about security risks, but other options are almost always preferable.

It’s equally quick and easy to send a file via a link instead, which allows you to control who can see it, as well as adding extra security like password protection. And if you’d like to make a few edits to your file, there’s no need to generate a new link for your recipients. Simply save the updated file to Dropbox (keeping the same file name and saving in the same folder) and your recipients will be able to see your most up to date version.

Secure large file sharing tips for solopreneurs and small business owners

Once you’ve decided on a file transfer solution for your business, it’s important to keep your security in check. After all, there’s only one of you, and your business can’t afford to fall victim to a security breach or loss of data.

Here are some top tips for secure file sharing to keep in mind:

1. Use cloud storage, so that sharing and collaborating is as simple as copying a link

Remember that file transfer isn’t always necessary, and sharing via cloud storage can be a great way to stay on top of version control and manage file access.
With Dropbox, you can store your files in the cloud, allowing you to seamlessly collaborate with others or share access whenever you need to.

2. When you do need to transfer, make sure it's encrypted

File transfer encryption is an essential security measure that encodes data to prevent outsiders from being able to read or understand the data that is being transferred. Simply put, encryption protects the data in your file transfers from potential hackers.

That’s why every file you send with Dropbox Transfer is encrypted, to protect it from security threats.

3. Make a good impression—think about branded file transfer to showcase your solo business

First impressions matter, especially when your business is still in its early stages.

You’ve already put effort into creating a logo, a visual identity, and potentially even a website or social presence. Your file transfers shouldn’t be any exception.

With customizable branding for your transfer’s download page, you can be sure to make a lasting impression with your customers.

4. Remember to backup for an additional layer of file security

Even with cloud storage, your local data and files are still at risk. When your business lives and breathes on one laptop—your laptop—it pays to have a backup solution on your side.

Dropbox Backup creates a snapshot of the files and folders on your device, so you can revert back to a recent version of your data in the event of a critical error.
